Track

Track is an Erlang web server that will write HTTP GET requests containing properly formatted JSON and Base64 encoded data to a file (log.txt).

Example JSON:

{ "event": "Signed Up", "properties": { "distinct_id": "13793", "token": "e3bc4100330c35722740fb8c6f5abddc", "Referred By": "Friend" } }

Example Base64 encoding of above JSON:

ew0KICAgICJldmVudCI6ICJTaWduZWQgVXAiLA0KICAgICJwcm9wZXJ0aWVzIjogew0KICAgICAgICAiZGlzdGluY3RfaWQiOiAiMTM3OTMiLA0KICAgICAgICAidG9rZW4iOiAiZTNiYzQxMDAzMzBjMzU3MjI3NDBmYjhjNmY1YWJkZGMiLA0KICAgICAgICAiUmVmZXJyZWQgQnkiOiAiRnJpZW5kIg0KICAgIH0NCn0=

Testing endpoint:

http://localhost:8080/esi/my_esi:track?data=ew0KICAgICJldmVudCI6ICJTaWduZWQgVXAiLA0KICAgICJwcm9wZXJ0aWVzIjogew0KICAgICAgICAiZGlzdGluY3RfaWQiOiAiMTM3OTMiLA0KICAgICAgICAidG9rZW4iOiAiZTNiYzQxMDAzMzBjMzU3MjI3NDBmYjhjNmY1YWJkZGMiLA0KICAgICAgICAiUmVmZXJyZWQgQnkiOiAiRnJpZW5kIg0KICAgIH0NCn0=

The request will return an HTTP response with body 1 if the call is successful and the data is written to disk and 0 otherwise. In the above JSON example, the "event," "properties," and "token" keys are all required.
